Nice machine heads

I swapped these out on my Les Paul, perfect fit. The locks work great and they are very smooth tuners that stay.

Grover Roto-Grip Full-size Locking Guitar Machines

These machine heads are fantastic and the finish is beautiful. I install them on all my guitars with temolo systems and are the exact replacement for the regular Grovers used on Gibson Les Pauls. Absolutely no slippage when tremolo is applied. I have purchased the gold and chrome ones and they match beautifully the hardware on the guitars.

Second Set-Plus and Minus

These were ordered for my own Epi Dot. The minus is weight-for me, this is the only negative. I have always had good results with Grover products. This guitar had the first set of Grovers that lost tune. The locking feature was partly from frustration, but I knew that a Bigsby was in the future for this guitar. I fully lock after a couple of winds with overlap. I view this as a protection from cutting-the ultimate clamping is "cushioned". It takes some extra time for the tune to settle but I consider this to be tolerable. I have the option to bypass those wraps. As noted by others, one must use discretion in backing off the thumbwheel to avoid having the "guts" fall out-one cannot be mindless-my brain works well enough that being warned, it has never happened.

Hard to Do Better

Grover lockers are some of the best out there. Guitars go in tune quick, and they stay there. I have never had a set fail one me. Between these and Hipshot, you should have all of your needs covered.

Grover full size locking tuners

I have put three sets on three guitars in the last few years and I just love them. The Les Paul is just a great fit for these tuning machines. It's one less point to not worry about, staying in tune, with these baby's are just no problem. Peace of mind.

No Nickel Finish? Why different dimensions?

The product seems decent but if you look at the specs tab you will see the differences in dimensions vs. the "original" full size grovers. Why do this? Wouldn't the market for the locking tuners typically be as an upgrade to replace standard non-locking grovers? Why not make them and perfect match and why not offer them in the same finishes - i.e. NICKEL (which I have) is not offered in the roto grip.

At first I thought the roto's were slightly larger but they are actually slightly smaller than the originals - making them slightly larger might make sense to "cover" any marks in the finish left by the originals. But smaller? I can't think of a reason.

I didn't ding the "star rating" but It seems like it would be a no brainer to make them the same exact physical specs for a perfect drop in replacement.

Grover Roto-Grip Full Size

This is an awesome product! It fits perfectly into
A Gibson Les Paul that is already stocked with regular Grover's. But if you install on a Gibson with the original tunning pegs, you will be able to see the top screw holes from the originals.

Top shelf

Great tuners: very easy string change, precise tuning, and keeps by Les Paul in tune even after using the Bigsby a lot and hard during a tune.
